SPRING-BED.

SPECIFICATION forming part Of Letters Patent No. 281,789, dated July 24,1883.

Application filed October 9, 1882. (No model.) Patented in CanadaOctober 18, 1882, No. 15,613.

To aZZ whom it may concern: Be it known that I, STANISLAS PARIsnAULT, ofthe village of St. John Baptist, in the county of Hochelaga, in theProvince of Quebec, in the Dominion of Canada, have invented a new anduseful Spring-Bed, and of which the following is a specification.

My invention relates to improvements in spring-beds in which slats onlyare used as springs and the objects of my improvements are, first, toprovide a permanent means to remedy the sinking that spring-beds willalways take after being in use for some time; second, to affordfacilities for the cleaning and the transportation of the spring-bed. Iat tain these objects byputting together the clifferent pieces formingthe spring-bed in the manner shown in the accompanying drawings, inwhich-- s Figure l is-a perspective View of the complete springbed; Fig.2, a plan of its flexible part, or of the slats, and Fig. 3a plan of itsframe or support.

In these figures the same letters refer to similar parts.

The spring-bed is made of two distinct and independent parts-viz. theframe represented in the drawings by Fig. 3, and the flexible partrepresented by Fig. 2.

The supports A and B are not of the same height. A, being the one placedat the head of the bed, is higher than B, so as to give the bed a slightinclination and render it more comfortable. These two supports A and Bare maintained at proper distance by two longitudinal pieces, 0 C, whichpieces are fastened to the supports by bolts or large screws. B can beattached on the longitudinals C G at three different places, and to thiseffect two additional holes, 6 z, are bored in C 0, one on each side ofthe support. arrangement is to provide a means to augment or diminishthe elasticity of the flexible part by lengthening or shortening thespace between the supports A and B. 111 the support A are firmly driven,at equal distances, as many dowels E E as there are slats in theflexible part. These dowels project on the upper face of the support toa length equal The object of this I to the thickness of the slats G.Near each extremity of the support Bis attached a latch, F. The dowels EE and the latches F Fhave for effect to maintain the flexible part inposition on the frame without fixing it permanently.

D is a transverse bar, fastened by two screws to the longitudinals, O O,and preventing the slats taking a too great deflection and breaklng.

011 the upper face of the supports A and B bands of woolen stuff or ofrubber are permanently secured to prevent the spring-bed from creaking.

The flexible part illustrated by Fig. 2 is composed of narrow, thin,elastic slats G G, bound together by one or more ribbons, H H H. Theslats are made stronger at their center than at their extremities, andthis surplus of strength can be given to them either in thickness or inwidth. At each end of the slats are bored holes large enough for thedowels E E. The slats are fastened on the ribbons H at equal distance,and in such a way that the holes will exactly fit upon the dowels E E.When the flexible part is in position 011 the frame the dowels E are inthecorrespondingholes in the slats, and thelatches F in the two outsidespaces between the slats, and turned 011 the two outside slats. Torestore to the spring-bed its original elasticity when the slats havebecome sunken by usage, the flexible part has only to be turned over.This may be done in two waysviz., by changing sides and reversing endsat the same time, or by changing sides only. The slats, not beingattached to the frame, are easily cleaned when needed, and put in abundle with the frame, which is taken apart by unscrewing four or sixbolts.

All the pieces of this spring-bed may be made of metal without changingany of the principles set forth in the above specification,

I am aware that prior to my invention spring-beds have been made ofslats. I there fore do not claim the usage of such slats; but

What I do claim as my invention, and de sire to secure by LettersPatent, is

1. In spring-beds, the longitudinals G C, 011

amass which the support B can be attached at three frame with a flexiblepart not permanently atdifferent places, M, substantially as described,tached together, for the purpose of giving a and for the purpose setforth. constant means of restoring to the spring-bed,

2. In spring-beds, a support, A, having by reversing the flexible parton the frame, 15 5 dowels E E, and a support, B, having latches itsoriginal elasticity, all substantially as said F, substantially asshown, and for the purpose before. set forth.

3. The slats G, having holes at both extreini- STANISLAS PA'RISEAULT'ties, for the object set forth, substantially as \Vitnesses: 10described. PATRICK J ORMAN,
